Woot.com has a pretty stellar deal on a 4.3-inch widescreen TomTom GPS system at $109, today only.
It’s a refurbished XL340-S unit with touchscreen, text-to-speech, lane guidance, and intelligent re-routing. The cheapest I could find it elsewhere was $126.95 (also refurbished) at Amazon and it was out of stock there.
Shipping from Woot.com is $5 and the unit carries a 180-day warranty direct from TomTom.
